This paper investigates the role of foreign direct investment (FDI) firms with respect to various economic aspects in developing countries, such as the determination of wealth distribution and the entry and exit of entrepreneurs. The model used in this paper is based on the theoretical framework...

This study examines the technical efficiency and productivity of 18 major domestic and foreign financial institutions in Cambodia during the period of 2006 to 2011. Data envelopment analysis was employed to estimate the efficiency of business operations and the Malmquist productivity index was...

In this paper, we consider an economy with producers and introduce a kind of "money" into the economy in order to incorporate producers' behaviors of profit maximization. We define a modified concept of "rejective core" which depends on both consumers' and producers' criterions, and prove the...

We present a formulation of the hybridized DGFEM with lifting operator for the plane elasticity problem. To validate the formulation, we establish an inequality of the Korn type by following the method of proof due to Brenner [Math. Comp., 73 (2004), 1067–1087]. Using the inequality, we can...

It is widely known that structural break tests based on the long-run variance estimator, which is estimated under the alternative, suffer from serious size distortion when the errors are serially correlated. In this paper, we propose bias-corrected tests for a shift in mean by correcting the...

This study proposes constructing a confidence set for the date of a one-time structural change using a point optimal test. Following Elliott and Mler (2007), we first construct a test for the break date that maximizes the weighted average of the power function. The confidence set is then...

In this paper, we analyze the formation of trusting relationships among people through communication. To foster trusting relationships, individuals must disclose private and personal information. However, disclosing such information has both costs and benefits; therefore, both parties must...

The cost of nuclear power generation critically depends on the damages caused by plant failure. We estimate the residential land damage caused by the failure of the Fukushima Daiichi nuclear power plant, as it forms a substantial part of the total damage, by observing the change in transaction...

This paper considers the conditional sum of squares estimator (CSSE) for the moderate deviation MA(1) process that has the parameter of the MA(1) with the distance between the parameter and unity being larger than O(T -1). We show that the asymptotic distribution of the CSSE is normal, even...

By using the empirical likelihood (EL), we consider the construction of pointwise confidence intervals (CIs) for nonparametric nonlinear nonstationary regression models with nonlinear nonstationary heterogeneous errors. It is well known that the EL-based CI has attractive properties such as data...
